碩士 / 國立高雄海洋科技大學 / 輪機工程研究所 / 104 / In response to increasingly tough international environmental regulations and rising oil prices, the development of marine diesel engines, worth exploring in depth for. At present the mainframe manufacturers are mustering their efforts to develop high-performance fuel-efficient, saving energy and environmentally friendly hosts. The heart is the host of the high-pressure fuel injection system, fuel injection performance upgrade if the better to promote as much as possible to achieve complete combustion of fuel, so that more output horsepower can save fuel and reduce pollution of its ultimate goal. The diesel engine fuel injection after the high-pressure pump to generate sufficient pressure fuel injection pressure to the cylinder, either double or oil-type injection pump injection pressure, injection amount and injection timing by the fuel injection pump are the control, fuel pressurized by each line to the injection nozzle, and the high-pressure injection pump is a mechanical action, so that is a period of time after the parts wear out, thereby affecting the injection timing, injection pressure and injection quantity, to solve this problem, and ultimately the formation to produce high-pressure common-rail fuel injection system, the type of engine operating mode to a computer to be monitored, so the timing, injection quantity and the injection pressure can be controlled in a jet full domain of the most appropriate, complete combustion and reduce emissions, the province in order to achieve the advantages of oil and improve the performance of the engine. Marine diesel power after years of fierce competition in the shipping market, and gradually form a MAN B & W (the electronic control type of high-pressure fuel injection system) and Wärtsilä-Sulzer (RT-flex), led by two world-renowned brands. This paper will examine the highest market share of these two marine main factory, how to improve the combustion efficiency of energy-saving win performance through high-pressure common rail fuel injection system.
